◆ dft_get_orbs()

void dft_get_orbs ( int  nvclen,
ergo_real gao,
const ergo_real(*)  coor[3],
int  nblcnt,
int(*)  iblcks[2],
int  nder,
const BasisInfoStruct bis 
)

Computes values of basis functions at specified points in space.

Only b.fs specified by iblcks[nblcnt] are computed.

Parameters
nvclennumber of points to consider. IT must be smaller than DFT_MAX_BLLEN.
gaomatrix of computed b.f, values. Dimension is in C convention: [nderivatives][nvclen], where nderivatives is 1 for nder==0, 4 for nder==1.
coorpoint coordinates.
nblcntso many continous blocks of basis functions will be computed.
iblcksstart and end indices of the b.fs shells. Computed shells are [iblcks[0], iblcks[1]).
nderwhether orbital derivatives are to be computed as well. Allowed values are 0 (no derivatives) and 1 (values and first order derivatives).
bisstructure describing the basis functions to be evaluated.
